Hormone Replacement Therapy for Transgenders Do’s and Don'ts Steven M. Brown, MD University of Wisconsin School of Medicine stevethediseaseslayer@yahoo.com
What is a Hormone? • Organic compound, secreted by a gland, in minute quantities, into the bloodstream, that has a regulatory effect on the metabolism of tissue or organs at a site different than the site of secretion • Alter the metabolism of cells or the synthesis and secretion of other substances (“tropic hormones”) • Bind to receptors (specific proteins) to “turn on” functions in target tissues
Endocrinology 101Glands: Groups of cells which specialize in the secretion of hormones • Some important glands • Pituitary • Anterior pituitary • Growth hormone • Thyroid stimulating hormone • Adrenocorticotropic hormone (ACTH) • FSH • LH • Prolactin
Additional glands • Thyroid • Pancreas • Insulin • Hypothalamus • Parathyroid glands • Adrenal glands • Cortisol • Testosterone • Estrogen • Aldosterone
The “sex glands” • Ovaries • Progesterone • Estrogen • Regulate reproduction, bone metabolism, regulation of blood cholesterol, breasts, skin • Testes • Testosterone • Regulates reproduction, musculature, bone metabolism, cholesterol levels, red blood cell production
Chemical origins of sex hormones • Derived from cholesterol • Chemical structures of estrogen, progesterone, testosterone vary slightly • Testosterone is a metabolite of progesterone • Estrogen is a metabolite of testosterone • Production is governed by negative feedback loops • Present in males and females in differing concentrations
Changes which occur in puberty • Pre-wired biological clock, probably in the hypothalamus, coincides with practical reproductive considerations • Hypothalamus releases Leutinising Hormone-Releasing Hormone (LHRH). • LHRH passes down nerve endings, stimulates pituitary gland • In girls, around age 10 to 13, FSH and LH are produced—starts the cyclic activity of the ovaries in the production of estrogen • In boys, ages of 10 and 14 years, FSH and LH “switch on” testicular function in males (FSH triggers sperm production), LH triggers testosterone production
Why Use Hormone Replacement? • Change physical appearance to maximize consistency between physical identity and internal gender identity • Assist in “passing” • Create better skin and hair patterns for subsequent cosmetic surgery such as facial feminization • Assist FTM transgenders with “beard growth” • For emotional well-being
What are some of the obstacles to HRT? • Patient issues • Ambivalence, “coming out” issues, fears of violence, fears of rejection, discrimination, social stigmatization • Not transsexual or not intensely transsexual • Financial considerations “social and economic marginalization” • Access to health care • Mistrust of medical establishment • Ability to have sustained follow-up and monitoring • Medical/behavioral contraindications • Underlying disease states • Unfavorable family history • Unfavorable lifestyle (tobacco, alcohol)
What are some of the obstacles to HRT? • Health care provider issues • Lack of education • Lack of clinical experience • Relative paucity of studies • Unanswered questions • Personal discomfort • Serious complications • Fear of litigation • Off-label administration of medications
Who Prescribes Hormone Replacement? • Primary care physician • Internist • Family Practitioner • “Gender dysphoria” clinic • Endocrinologist • Gynecologist • Urologist • SRS Surgeon • Psychiatrists
Who SHOULDN’T Prescribe Hormones • Yourself • Family • Friends • Internet “buddies” • “Urgent care” physicians • “On-line” doctors • “On-line” pharmacies
Where Transgenders Get Hormones • “Black Market • Friends • Mexico • Internet • Local pharmacy
SOME IMPORTANT WARNINGS • NEVER use hormonal medication prescribed for another person • DON’T self-medicate • Use caution in purchasing hormones from “Black market sources”, the Internet, foreign countries, mail order houses and vendors who can “get it or you” • Medication may be impure • May be contaminated • Temptation to bypass appropriate monitoring
SOME MORE WARNINGS • Don’t double dose • Don’t alter regimen without supervision
An HRT “Do” • A clinician should collaborate with a mental health specialist who has extensive experience with the diagnosis of such patients to avoid mistreatment with hormones or sex-reversing surgical procedures
Standards of Care: Harry Benjamin International Gender Dysphoria Association: • Requirements for HRT in adults • Age 18 or older • Demonstrable knowledge of what hormones can and cannot do • Knowledge of social benefits and risks • Documented real-life test for at least 3 months before HRT or • Period of psychotherapy of duration specified by a mental health professional (usually 3 months) • A letter from the mental health professional to the prescribing physician www.hbigda.org.
Some important principles • There is a lot of misinformation, especially on the Internet • Hormone therapy remains somewhat “hit and miss” • “Individual results will vary”, especially for MTF • Extremely important to let any treating physician and pharmacist know of all your medications to avoid “drug-drug” interactions and to reduce potential complications • Need to keep spouse/significant others informed
Reproductive options • To give opportunity to obtain children who are genetically “their own” • Sperm banking prior to HRT for MTF • FTM’s banking of ovarian tissue or oocytes • Embryo banking Gender reassignment and assisted reproduction, Human Reproduction16: 612-614 (2001)
“Real-Life Test” Pros and Cons • Pros • HRT can cause permanent changes including sterility and gynecomastia. RLT may confirm that transitioning is the right choice • Cons • HRT makes it easier to pass and easier to attempt RLT • Most people who would consider hormones are pretty sure of what they want by that time • HRT is “diagnostic” itself—true transsexuals will feel calmer and relieved upon starting HRT; if not truly transsexual, changes will cause worsening anxiety
Purposes of Feminizing Hormones • Induce the development of female secondary sexual characteristics • Anti-androgen treatment to reduce the effect of endogenous male sex hormones
Feminizing Hormones DO NOT • Cause the voice to increase in pitch. • Dramatically reduce facial hair growth in most people. There are some exceptions with people who have the proper genetic predisposition and/or are less than a decade past puberty. • Change the shape or size of bone structure. However, they may decrease the bone density slightly.
Some important DO’s • DO review risks and benefits before starting any hormones • DO be sure that this is what you really, really want…permanent changes can occur within weeks • DO be patient • DO eat healthy and exercise • DO reduce alcohol intake (reduce stress on liver)
Some important DO’s • DO have regular medical checkups (every 2-3 months) • DO watch your blood pressure • DO take a good multi-vitamin/mineral supplement to help be sure the body has everything it needs for new development • DO give the body time to adjust • Use the lowest hormone dosage that affords the desired changes. • DO make sure you are not allergic to Provera tablets before you use Depo-Provera sustained release intramuscular injection • DO drink fluids, watch potassium intake if taking spironolactone
Some important DO’s of Doctoring • DO see a reputable doctor for your care • DO get regular check-ups • DO be honest and up front with your doctor about all medications • DO make a list of questions prior to each visit—don’t be afraid to ask questions • EDUCATE your doctor, especially if you disagree • DO keep records of all changes—physical and emotional, and SHARE them with your doctors • SEE your doctor for any discharge from breasts
Some important DON’TS • DON’T go out on your own for meds • DON’T alter your medication regimen • DON’T BUY hormones on the Internet or through Mexico • DON’T BELIEVE everything you read on the Internet, including web pages, bulletin boards, and chat rooms • DON’T let your weight get out of control • DON’T smoke • DON’T taking the maximum planned dosage of all hormones at once • DON’T take pre-operative dosages of hormones for more than about 3 years
Effects of Feminizing Hormones on Males • Effects vary from patient to patient—familial, genetic tendencies • Younger patients generally obtain and more rapid results • Noticeable changes within 2-3 months • Irreversible effects within 6 months • Feminization continues at a decreasing rate for two years or more, often with a “spurt” of breast growth and other changes after orchidectomy
Effects of Feminizing Hormones on Males • Breast development • can take years, begins after 2-3 months • final size about 1 to 2 cup sizes less than close female relatives • less satisfactory results in older patients • Only one-third more than a “B”-cup • 45% don’t advance beyond an “A” • growth not always symmetric • Larger male thorax “dilutes” effect • enhanced by progesterone • nipples expand • areolae darken clevelandplasticsurgery.com
Effects of Feminizing Hormones on Males • Loss of ability to ejaculate/maintain erection (variable) • Fertility and “male sex drive” drop rapidly—this may become permanent after a few months • Increased female-type sex drive/attraction to men
Effects of Feminizing Hormones on Males • Decreased testicular size (mostly flaccid) • The prostate shrinks but does not disappear and prostate cancer is still possible (although risk is reduced) • DO HAVE REGULAR PROSTATE EXAMINATIONS • Decreased penis size, scrotal size (25% within first year), sometimes requiring the patient to stretch by hand to maintain adequate donor material for SRS • Spontaneous erections suppressed within 3 months (but not totally eliminated)
Effects of Feminizing Hormones on Males • Decreased facial/body hair • Body hair lightens in texture and color, frequently disappears • Cessation of male pattern baldness • Limited regrowth of scalp hair which has been lost • Improvement in thickness and texture of scalp hair • Enhanced action of 2% or 5% minoxidil (Rogaine®) • Not much effect on distribution of facial hair • Enhanced effect of electrolysis • Decreased rate of growth
Cutaneous Effects of Feminizing Hormones on Males • Redistribution of body and facial fat • Face looks more “feminine”—reduced angularity, fuller cheeks • Redistribution of fat from waist to hips and buttocks • Skin softer/smoother/thinner, more translucent, less greasy • Skin sometimes becomes excessively dry • Improvement in spots and acne • Redistribution of fat to hips and buttocks • Brittle fingernails • Increased susceptibility to scratching and bruising • Tactile sensation becomes more intense • Oil and sweat glands become less active, resulting in dryer skin, scalp, and hair
Effects of Feminizing Hormones on Males • Sensory changes • Heightened sense of touch • Increased sense of smell • Emotional changes • More labile
Effects of HRT on Metabolism in MTF’s • Metabolism decreases • Given a caloric intake and exercise regimen consistent with pre-hormonal treatment • Weight gain • Decreased energy, • Increased need for sleep • Cold intolerance
Other effects of hormones • Reduced risk of Alzheimer’s • Improved memory
Effects of Feminizing Hormones on Males • Loss of muscle mass • Loss of strength • Estrogen prevents bone loss after testosterone deprivation Long-term follow-up of bone mineral density and bone metabolism in transsexuals treated with cross-sex hormones, Clinical Endocrinology, 48: 347-354
Changes in Sexual Orientation “Of 20 transsexuals of various types that were interviewed, 6 heterosexual male-to-female transsexual respondents reported that their sexual orientation had changed since transitioning from male to female…three of the respondents claimed that the use of female hormones played a role in changing their sexual orientation.” Daskalos CT. Changes in the sexual orientation of six heterosexual male-to-female transsexuals. Arch Sex Behav. 1998;27:605-614
Risks of Feminizing Hormones —Some General Principles • Complete risks in transsexuals is not known • Most studies are performed in biological women • Limited research regarding risks • Safety data and Food and Drug Administration approval do not acknowledge the use of hormones in transsexuals • All administration is thus “off-label” • Mortality not necessarily increased
Risks of Feminizing Hormones • Blood clots— • 12% over age 40 • Usually start in the veins of the legs • Can break off and block blood supply to the lungs—a FATAL complication (pulmonary embolism) • 20-fold increased risk in MTF’s • Risk increased with oral vs. transdermal estrogens • Central retinal vein occlusion has been reported Mortality and morbidity in transsexual subjects treated with cross-sex hormones, Clinical Endocrinology, 47: 37-342 (1997)

Reducing the Risk of Blood Clots • Smoking cessation • Pharmacologic support • Relaxation therapy • Behavioral therapy • Discontinue HRT for 3-6 weeks prior to any major surgery, including SRS • Review HRT with surgeon and anesthesiologist prior to minor surgery • Discontinue HRT in injuries which result in immobilization
Risks of Feminizing Hormones • Fluid retention • Prolactin • 14%, in one study developed elevations • Pituitary enlargement can sometimes require surgery • Hypertension • May vary with hormone regimen Mortality and morbidity in transsexual subjects treated with cross-sex hormones, Clinical Endocrinology, 47: 37-342 (1997)
The Cardiac Risks of Feminizing Hormones • Most studies have and are being done in biologic women • Much evidence suggests that estrogen lowers cholesterol levels, and raises HDL (good cholesterol) • Increases triglycerides, blood pressure, subcutaneous and visceral fat • Decreased LDL particle size (bad) • Decreased insulin sensitivity (bad)
Estrogens and the Heart • Current studies • Women’s Health Initiative • 27,500 enrollees without CAD to test estrogen or estrogen plus progestin post-hysterectomy • Women’s Angiographic Vitamin and Estrogen • Women’s Estrogen/Progestin and Lipid Lowering Hormone Atherosclerosis Regression Trial (WELL-HART)
Hormones and the Heart • JAMA: July 17, 2002 • “Risks and Benefits of Estrogen Plus Progestin in Healthy Postmenopausal Women” • 16,608, ages 50-79 studied • Received placebo or Premarin® plus Provera® • Study stopped after 5.2 years because of significantly increased risk of cancer in treatment group • Reduced risk of colorectal cancer and hip fractures • Increased risk of coronary artery disease, pulmonary embolism, stroke
Hormones and the Heart • What is the risk-benefit ratio in post-menopausal women? • Decreased hot flashes • How does the risk-benefit ratio differ in transgenders? • Physical feminization • Reduced emotional stress
